DOUBLE-WALLED VESSELv Specificatiom of Letters Patent.

Patented June 1,} 909.

Application filed May 11, 1908. Serial No. 432,174.

To all whom it may concern:

, Be 't known that I, GEORGE P. ALTEN- BERma citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and .useful Improvements in Double-\Vall.ed Vessels, of which the following is a specification.

It is the object of my invention to provide {a double walledvessel comprising an inner member and an outer member connected at latter Figure 1 is a central vertical section of my V blocks.

improved device showing the separating means as compris ng separated parts or Fig. 2 is a horizontal section of the sameon the line rc-mof Fig. 1. Fig. 3 is a "central vertical section of my improved device, showing the se arating means as comprising a disk orwas er between the bases of the members of the vessel; and, Fig. 4 is a perspective view of the disk or Washer.

' x -1 represents theiniier member of the vessel an 2-the outer member thereof, which i are preferably connected at the mouth 3 for forming a space 4 between the members.

' T he Vessel is preferably formed of glass, the

" space surrounding the inner Vessel.

This

flspace is a heat-insulating space and the air in t is preferably withdrawn or practically exhausted for forming a vacuum. ,may be withdrawn through a nip le 5 which is afterward sealed. The wall 0 the space 'jmay be provided with suitable silvering soi of the vessel.

lution.

innervessel, wiicli depending and laterally extending portions are preferably annular about the axis of the inner vessel and form a seat 10, shown annular, between the depression 7 and the outer portion of the base of the inner vessel. The depression 7 is preferably cup-shaped anda iarl. of the (ori tcntsereceiving portion of t in inner member A separating device l l is received in the seat and preferably roinli l 'bieees I). The outer n'ivi ler is provided with a base lI-l arranged to act with the depending portion 8 and the laterally extending portion 9 of the base of the inner member for retaining the separating means or support in the seat 10 against vertical displacement, or shifting up ardly or downwardly. The bases of the inner and outer members preferably converge as shown at 14 15 at the respective sides. of the separating means.

In order to prevent shifting of the separating-pieces about the axes of the members I prefer to mount them on awire 16, shown as a ring, and I prefer also that the separating-device or support shallbe. located between the bases of the members of the vessel Within the longitudinal projection of the Wall of the inner member thereof. If desired the separating means may take the form of a,

other materials may be employed. The ma-- terial of the washer, such as asbestos, is porous, and permits the air in the spec-ethereabove to be readily drawn through its pores foir exhausting said space through the nipp e 5.

By means of my improved device the members of the vessel are-supported from each other by separating means between their bases so that the inner member may receive longitudinal support from the outer member, and the/mom )ers may also receive relative lateral su )port at their bases, and

I prefer that the v use of the inner member shall have the depression extending into and past the lateral planes of the separating device, and l further prefer that said depression shall be free of support from the outer base adjacent thev longitudinal axes of saidinembers.

In some sizes of vessels it also desirable to have a separator or separators between the members of the vessels intmmediate of their lengths between their bases and the neck-of the vessel, for supplying intermediate support for said vessels, and I prefer to aceoinplish this by providing separating-blocks id in the space between the members of the vessels internimliate of the length of said mem bone, which blocks are preferably mo unted on a wire l9 wh ch may be in the form of a ring of sush -size as to press the blocks l8 against the inn r vessel.

llll) said outer member having a depending por- Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

1. A double walled vessel com rising in combination an inner member an an outer member connected at the mouth of said vessel and having heat-insulating space between said members, and separating means between the bases of said members, the base of said inner member having a depending contents-receiving portion about which said separating means are located, the base of tion surrounding said separating means anddepending ortion of said inner member, and said depending portions of said bases of said outer and inner members being within the longitudinal projection of the wall of said inner member.

2. A-double walled vessel com rising in combination an inner member an an outer member connected at the mouth of said vessel and having heat-insulating'space between said members, separating means between the bases of said members, the base of said inner member having a do )ending contents-receivin g portion about which said so 7 arating means are located, the base of t c said outer member having a depending portion surrounding said s e )arating means and depending ortion of sai inner member, and said depen ing portions of said bases of said outer and inner members being within the longitudinal projection of the wall of said inner member, and separating means between said members intermediate of their lengths and outside the longitudinal projection of the wall of said inner member.

3. A double walled glass vessel comprising in combination an inner member and an outer member connected at the mouth of I sald vessel and havlng heat-insulating space i therebetween, said members having bases, thebase of said inner member having a cupshaped' depression, the base of said outer member surrounding said on -shaped depression, and separating means ocated about said cup-shaped depression between said bases and within the longitudinal projection of the wall of said inner member.

4. A double walled vessel com rising in combination an inner member an an outer member connected at the mouth of said vessel and having heatinsulating space therebetween, said members having bases provided with longitudinally extending depressions within the longitudinal projection of the wall of said inner member, and separating means between said depressions located about the longitudinal axes of said members and within the longitudinal projection of the wall of said inner member.

5. A double walled vessel com rising in combination an inner member an an outer member connected at the mouth of said vessel and having heat-insulating space thereb'etween, said members having bases, the base of said inner member having a cupshapeddepression, the base of said outer member surrounding said cup-shaped depression separating means between said bases and within the longitudinal projection of the wall of the said inner member, and additional separatingmeans between said members intermediate of their lengths and outside the longitudinal projection of the wall of said inner member.

In testimony whereof, I have subscribed my name hereto in the presence of two subscribing witnesses.
